Superram build

I picked up a complete Superram from a board member here and I think I have a pretty good matched combo. 355 10.25:1 compression, Superram (complete) flows 240cfm mated with Trick Flow 175cc heads 242cfm with a Comp XE268 224/230 duration, 1.6 rockers, Stainless works 1 3/4 longtube headers, custom dyno tune and no emissions. Im guessing 320rwhp. That would be about 380 crank hp considering a 20% drivetrain (700r4) loss. Numbers sound about right for this combo?
